The invention discloses an order processing method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of capturing order information in real time, obtaining user related data of the order information, and obtaining feedback stream data; wherein the feedback stream data is used for optimizing processing logic of abnormal order detection; constructing first order rich data according to the order information, the feedback stream data and the user related data; determining topological information associated with the first order rich data by using a preset graph structure strategy; and determining abnormal order rich data in the first order rich data based on the topological information and the first order rich data, and intercepting the order information corresponding to the abnormal order rich data. According to the embodiment, the accuracy and response speed of abnormal order detection are improved, and the occurrence of fraudulent behaviors is effectively reduced.

The invention discloses a financial reimbursement method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining applicant information and a reimbursement file submitted by a reimbursement applicant, and the reimbursement file comprises an invoice file and a payment record associated with the invoice file; obtaining consumption items in the invoice file; extracting a target field in the payment record; determining a consumption item corresponding to the payment record based on the target field; whether matching; if the invoice file is matched with the payment amount and the consumption item of the payment record, performing reimbursement processing on the reimbursement file based on the applicant information and the payment amount and the consumption item of the invoice file; and if not, determining that the reimbursement file does not pass the verification. In the stage that the applicant submits the reimbursement file, the matching degree of the payment amount and the consumption item of the invoice file and the payment record is automatically checked, the phenomenon that the payment amount of the invoice file and the payment record is matched but the consumption item is not matched can be avoided, and the occurrence probability of financial fraud and errors is reduced.

The invention provides a cross-border trusted trade collaboration system and method based on a block chain and related equipment. The system comprises a block chain data layer which realizes block chain cross-chain data exchange of sea transportation lading orders during cross-border trusted trade based on an intelligent contract of an alliance chain; and a sea transportation lading bill service application layer, the sea transportation lading bill service is accessed to the block chain data layer based on an adaptive framework, and the sea transportation lading bill is used in the sea transportation lading bill service application layer. According to the method, the authenticity verification requirement of the sea transportation electronic lading bill data is met through the Hash value interacted on the chain; by combining the alliance chain and the smart contract, the safety, efficiency and compliance of cross-border trade are improved.

The invention discloses a staff medical insurance common outpatient service supervision system based on a medical cost and knowledge graph, and relates to the technical field of staff medical insurance common outpatient service supervision. Comprising the steps of collecting and analyzing staff medical insurance common outpatient service supervision data, comprehensively analyzing, optimizing and adjusting. According to the invention, by collecting and processing the staff medical insurance common outpatient service supervision data, analyzing, comprehensively analyzing, optimizing and adjusting the staff medical insurance common outpatient service supervision data, the security of the staff common outpatient service overall planning medical insurance fund is improved, and the problem that the security of the staff common outpatient service overall planning medical insurance fund is insufficient in the prior art is solved.

The invention provides a source code integrity detection system based on a distributed account book technology, and the system comprises at least two distributed account book nodes which are used for carrying out the compiling of a source code in the nodes, and the compiling at least comprises the compiling, modification and detection of the source code; each distributed account book node comprises an account book receiving module used for receiving a distributed source code account book published in a network; the code detection module is used for compiling source codes in the distributed source code account book; and the account book sending module is used for sending the compiled source code to the network in a broadcast form. According to the method, the source code is subjected to integrity detection based on the distributed account book, and the risk of fraud and errors can be greatly reduced by means of the characteristic that the source code data cannot be tampered in the distributed account book; meanwhile, the automatic and efficient source code management process can shorten the development cycle, reduce the development cost, improve the quality and stability of software and promote cooperation and cooperation of different development teams.
